Forum Strange issue with Thread Display Options
 

When users, including me, try and use the "Thread Display Options" to change the thread view for the current forum we get the following error "Invalid Forum specified. If you followed a valid link, please notify the administrator".

I've search and search and have been unable to find the cause or any hit of a possible cause. I have not found anything in the VB logs , and I've tried a database clean-up. I have also checked all permissions, and I have the same issue with plugins disabled.

Any ideas?

Thank you,
